To alir whom it may concern: I

Be it known that I, OrrARLEs L. ,I-IEISLER,

Y a citizen of the United States of America, and

a residentof the city of Pittsburg, State of Pennsylvania, have made certain new and useful improvements in that class of pumps in which oppositely-arranged packing-boxes are usedin connectionwitha single plunger 01' shaft, of which the following is a specification;

My invention relates princilgellly to the construction of the plunger ac g or stufiing box, the object thereof eing to rovide an efiicient means for reventing lea age of air or water through tl ie stufling-box of outside-packed water-plungers by arranging a seal mainly between the main plunger stufiing-box and the adjusting-bolts'of said main stuifing-box. I

Figure 1 of the accom anying drawings illustrates .the most usua formof the im-' provement. Figs. 2, 3, and 4 show modifications thereof.

Numeral l is the plunger.

7 is the casing of the pump roper or plunger-chamber; 2,the mam st g-box; 4, the adjusting-bolts; 5, the telescopic plunger sleeve'and stuffer; 6, the auxiliary packlng for the plunger-sleeve 5, arranged in a box in the casing. v 8 is the usual nest of suitable (packingrings in'th'e box 2-in the casing an in con-- tact with the reciprocating plunger.

In the common form 0 outsideacked plun ers, where thereare two sets 0 packings or the usual op ositely-arranged ulsa-r tion chambers or cy inders, the atten ant is continually adjusting the double set of packings extremely ti ht to make it show a minidetecte .5

mum of external eakage, notthat this slight amount of water-leakage causes an appreciable waste, but because there is a leakage of air to the plunger-chamber, thereby causing destructive waters-hammer and the waterleaka e is unsightly, which he thinks reflects upon care of the urn On the other hand, the excessive frictional resistance due to tight dpackin is not soapparent or readily even y an expert, who, however, from many re eated tests knows of the great loss of power y friction in the double nest of packing used in the usual construction of outside-packed plungers, and therefore would insist on having a single nest of inside packing if the latter were readily accessible and externally adjustable for leakage. The obculty, and this I effect b sealing the joint between the sleeve and t e casin adjacent to the inside packin .thus' com the accessibility of the outside packingthat is,

justable stuffing-box tted with a single nest of packing set against the reciprocating plunthe sleeve and casing. I

The" main stuffing-box 2 is so it can be renewed or chan The plunger sleeve or stufl'er 5 is made cylindrical and adjustable endwise, one end enwhich makes a water-tight telescopic joint between the lunger-sleeve and plungerchamber 7. N 5 enters the main stuffing-box 2 is arranged a purpose of preventing leakage around the main-stuflin =box end of the lunger-sleeve or through t e main stuflingox to the ex{ terior of the pump, also to re'vent air from enterin along t e same route. Without the use'o ally force the plunger sleeve 5 very ti ht and hard against the causing excessive, 'ction on the lungers. {Evidently the seal 3 permits the packing 8 to e resu ts. When there. is an" undesirable amount of leakage past the packing-rings 8, it canbe detected by the hissing-noise made by water whenpassing through a 'small'cr'ev- .ice. In Figsvl and 2 thisseal is arranged directly upon the cylindrical shell of the plu er-sleeve 5. In Fig. 4 it is arranged on the ange 9 of the plunger-sleeve. In Fig. 3' it is arran ed adjacent to the plunger-sleeve and is he (1 place by'a suitable flanged stufier 10. In igs. 1,.2, and 4 most com :mon form ofpacking is used for the seal. "In Fig. 3 a cup ed leather packing forms the seal; In all t e fi ures the seal 3 is shown to be arranged mainIy between the main pack ing-box 2 and the adjusting-bolts 4, thereby iving ready access to the said bolts and eeping them free from the liquid pumped, which often causes excessive corrosion, parreferably made independent of the plun er-c amber 7, ed in size. This stufling-box is held in place y suitable bolts,

tering the main stuflin -box 2 and the other. end through an auxi iary stufiing-box- 6,

ear where the plunger-sleeve] the plunger-cham ers by -passin the seal 3 it would be necessary to continu-' acking-rings 8, t ereby Patented July 10, 1906.

'ject of this invention is to solve this difii- "good features of the inside packing wit the to provide an air-ti%ht and externallyad-I' ger, but with a pacln'ng at each endbetween roperly adjusted-for most economical 8o suitable seal, formed at 3. This seal is for-the ticularlgwhen pumping salt brine, acids, and liquids aving strong corrosive properties.

As shown, .the arran ement permits the use of a sin le main stu n -box 2, as in inside-packs pumps, thereby red friction one-dalf as compared with the usual .iforrn of outside-packed plungers flheadusting-bolts are arranged, as usual, withln the external leakage in case t e packing 8' is worn or destroyed. So no harm would result may have a rotative instead of reciprocating Y exce t the lossdue to the leak from one lunger-c amber to the other. In the usua construction of outside-packed plungers it would be necessary to immediately shut down, the

v ,as theair entering the pum would ins ta'ntly cause destructive .waterammer or prevent its operation. The seal 3 can be ormed, as shown in the several drawings, by

cutting a groove or making a small stuffing bex or recess and filling it with some yielding ki which may be metallic or fibrousi ently the plun er 1 may be in the form of a piston or p unger rod and which motion.
